自从1939年以后,电冰箱的制冷机约80％以上是采用封闭式的装置;它的构造方法是将电动机与压缩机密封在一个共同的钢皮壳内,使内部的机器与外间的空氣完全隔绝。这种机器的装置有如下的优点: 1.制冷剂绝对不洩漏,保证不损害健康。 2.使用比较安全,油料消耗极少,不需要检修 3.电力消耗较少,节省经常开支。 4.机器占用面积很小,启动时震动声音甚低。由于制冷机一经密封以后,不容易拆开进行修理,且须保证经久耐用,因此对于制造此种机器所
Since 1939, more than 80% of the refrigerators in refrigerators have been enclosed; they are constructed by hermetically sealing the motor and compressor in a common steel hull, so that the air inside the machine and outside is completely Isolated. The device of this machine has the following advantages: 1. Absolutely no leakage of refrigerant, to ensure no damage to health. 2. Use more secure, fuel consumption is minimal, does not require maintenance 3. Less power consumption, saving recurrent expenditure. 4. The machine occupies a small area, when the vibration sound is very low. Since the refrigerator once sealed, it is not easy to open for repair, and to ensure durability, so for the manufacture of such machinery
